On the web gui of Elastix or freepbx, I turn on "Enable Parking Lot Feature" and press "Submit Changes" and press the red bar "Apply Configuration Changes Here" on the top. I also check /etc/asterisk/feature.conf, parking_additional.inc those 2 files are ok. But parking lot function just is not working. How is that be happened? if I use trixbox 2.2.12, it's ok. But I like eastix more. Could anyone suggest some light way to me ? ps:I have read "Elastix without tears".
